Real-Time PCR of selected genes. PBMCs were isolated from 4 healthy volunteers (Control), from 10 SARS infected patients (SARS), and from 5 influenza virus infected patients (Influenza). Total RNA was extracted from all the samples and Light-Cycler Real-Time PCR was performed. The concentrations of these genes mRNA were calculated using respective standard curves. Lactoferrin expression (LTF); Lipocalin expression (Lipocalin); S100P expression (S100P); FCGR3A expression (FCGR3A); TLR2 expression (TLR2); Interferon Alpha expression (IFNa); Interferon Beta expression (IFNb); Interleukin 12-p40 expression (IL-12); Tumor Necrosis Factor Alpha expression (TNFa); and GAPDH expression (GAPDH). Results are expressed as average ± SD of gene expression for each group (control n = 4; SARS n = 10; and influenza n = 5).
